Abstract

Zur Erstellung eines dreidimensionalen Modells für ein real bestehendes Objekt wird das interessierende Objekt zunächst digitalisiert, um ein Netzmodell des Objekts zu erzeugen. Anschließend wird das Netzmodell in bilineare Flächenelemente zerlegt und diese schließlich wieder zu einem Flächen- oder Volumen-körper-modell vereinigt. Aus dem Flächen- oder Volumen-körper-modell lässt sich durch CAD/FEM-Kopplung ein Finite-Elemente-Modell erstellen. Die erzeugten Modelle sind nicht nur genau, sondern ihre Erstellung erfordert auch relativ wenig Rechenaufwand.
